"I got a little off track when I left 'Little House on the Prairie,'" the 75-year-old actress recently explained to KCAL. "There's nothing worse than someone having a lot of money and a lot of free time."

The actress recalled, with the help of diaries and datebooks, growing up in Hollywood in the early 80s, surrounded by drugs and alcohol.

"I was spending too much time playing," she said in an interview with Star Tribune.

She even recalls her passionate trysts with A-listers, including a romantic getaway with The Doors singer Jim Morrison.

"We made this great escape together," Stewart recalled about Morrison. "It was a really hard time in his life."

But the fun came to a crashing halt when she realized she had a problem.

"People were trying to help me, but I didn’t want to hear what they were saying. That’s common with addicts," she told the Star Tribune.

She recalled in the memoir that in her darkest period, she endured everything from cancer, to divorce, to financial ruin and homelessness. She even said drugs jeopardized her career.
